- Remove the pinion shaft locking bolt.
- On axles without a locking differential, remove the pinion shaft.
- On axles with a locking differential, remove the shaft part way. Rotate the case until the pinion shaft touches
the housing.
- On axles with a locking differential, use a screwdriver, or a similar tool, in order to enter the differential case and rotate the lock (1) until the lock
aligns with the thrust block (2).
- Remove the brake drum.
- Push the flange of the axle shaft in toward the differential.
